Furnace Repair for Green Country Homes and Businesses
Oklahoma winters bring temperatures into the twenties and thirties regularly from December through February, with cold snaps pushing into the teens or lower. A furnace failure during that stretch is more than uncomfortable. Pipes can freeze. Vulnerable family members, especially the elderly, infants, and anyone with health conditions, are at risk. And gas furnace problems carry the additional concern of carbon monoxide safety.
Cool Down Heating and Air repairs all types of residential and light-commercial furnaces, including gas, electric, and LP/propane models. Every repair is performed by our own technicians, backed by a written warranty, and includes a CO safety inspection at no extra charge. We also offer free second opinions on any repair recommendation.

Signs Your AC Needs Repair
Furnace Won't Turn On
Check your thermostat setting and circuit breaker first. If both look normal and the furnace still won’t start, the issue is likely a failed ignitor, a tripped safety switch, or an electrical problem. Call for a diagnostic.
Furnace Blowing Cold Air
If air is coming through the vents but it’s not warm, the burners may not be firing. Common causes include a dirty flame sensor, a failed gas valve, or a blower motor running without ignition.
Furnace Short-Cycling (Turning On and Off Rapidly)
Short-cycling strains every component in the system. It’s usually caused by a dirty filter, a bad flame sensor, an overheating heat exchanger, or a thermostat malfunction.
Unusual Noises (Banging, Popping, Screeching)
Banging often indicates delayed ignition (gas buildup igniting at once). Popping can mean expanding ductwork. Screeching points to a blower motor bearing. None of these should be ignored.
Yellow or Flickering Pilot/Burner Flame
A healthy gas furnace produces a steady blue flame. Yellow, orange, or flickering flames can indicate incomplete combustion and potential carbon monoxide production. This is a safety concern that requires professional inspection.
Common Furnace Repairs We Handle
- Ignitor and Flame Sensor Replacement
The most common furnace repair in modern systems. A dirty or cracked flame sensor prevents the burners from staying lit. A failed ignitor prevents ignition entirely. We carry these parts on every truck for same-visit repair.
- Heat Exchanger Inspection and Replacement
A cracked heat exchanger can leak carbon monoxide into your home. We inspect heat exchangers as part of every furnace repair and tune-up. If yours is cracked, we’ll explain your replacement options honestly.
- Blower Motor and Control Board Repairs
If the blower won’t start, runs constantly, or operates at the wrong speed, the motor or control board may need repair or replacement.A failed compressor is the most expensive AC repair. We’ll give you an honest assessment of whether replacement of the compressor or of the full system makes more financial sense. See our AC installation page for replacement options.
- Gas Valve and Thermocouple Replacement
Gas valves control fuel delivery to the burners. Thermocouples (in older systems) and flame sensors (in newer ones) tell the valve when to open and close. We diagnose and replace both.
Benefits of Professional Furnace Repair
CO Safety Inspection Included
Every furnace repair from Cool Down includes a carbon monoxide safety check. Gas furnaces produce CO as a combustion byproduct, and a cracked heat exchanger or venting problem can allow it into your living space. We check for this on every call.
Correct Diagnosis, Fewer Repeat Calls
We use proper diagnostic procedures and don’t replace parts by guessing. That means fewer callbacks, lower total cost, and a system that actually works after we leave.
Honest Repair vs. Replace Assessment
If replacement makes more financial sense than repair, we’ll tell you. We offer free second opinions on any recommendation. Furnace Installation details.
Written Warranty on All Work
Every furnace repair is backed by a written warranty. If the same problem comes back, we come back and fix it at no additional cost.
What a Furnace Repair Visit Includes
When you call (918) 527-6792, we dispatch a technician, typically same-day. On arrival, the tech runs a full diagnostic: testing ignition sequence, measuring gas pressure, checking the flame sensor and ignitor, inspecting the heat exchanger for cracks, testing the blower motor and control board, and measuring CO levels at the register and in the living space.
Once the issue is identified, you get a clear explanation and a written quote. We repair on the spot whenever possible. If the heat exchanger is cracked or the system is beyond cost-effective repair, we’ll walk you through replacement options. See our furnace installation page or our Emergency HVAC page for after-hours no-heat calls.
